How to Choose a Gas Grill? | Fuel, Size & Heat That Fit

Walk into any store and you will see dozens of models ranging from $100 to well over $6,000. The right choice is not the most expensive or the one with the highest BTU number — it is the grill that fits your fuel setup, your cooking volume, and your backyard. A three-burner grill with 450 to 500 square inches of cooking area is a safe bet for an average-sized family, but the real test is how evenly it holds heat and whether the materials will survive three seasons of outdoor use. This guide walks you through the decisions that matter, step by step.

Propane or Natural Gas: The First Decision

Pick your fuel type before you compare grills, because it determines portability, hookup cost, and which models you can consider. Propane is flexible — you can move the grill anywhere, and tanks are easy to swap. Natural gas requires a permanent gas line, but you never refill a tank or run out of fuel mid-cook. Most grills are sold for one fuel type, though some can be converted with a kit. Check compatibility before buying; a natural gas model cannot safely run on propane without the proper conversion parts.

Propane tanks are not always included with a grill purchase. If yours does not come with one, expect to add $20 to $30 for a standard 20-pound tank.

Size, Burners, and Who You Cook For

Match the cooking area to the number of people you regularly feed. A couple or small family can manage well on 300 to 400 square inches. Most families need 450 to 500 square inches. If you frequently cook for larger groups — think 8 to 12 people — aim for 550 to 650 square inches.

Burner count follows the same logic. Three burners are enough for many households. Four to five burners suit larger regular gatherings and give you more zones for indirect cooking. A grill with 2 to 6 burners is the current range on the market. More burners usually mean more space, not necessarily better performance — a well-designed three-burner grill can outperform a poorly-made four-burner model.

If you are looking for a dependable starting point, our top picks for entry-level gas grills focus on models that balance size, heat control, and durable materials without the price tag of premium units.

Heat, BTUs, and Build Quality

BTUs are the most-cited spec but the least useful on its own. Many current gas grills fall in the 25,000 to 60,000 BTU range. A rough metric is about 110 BTUs per square inch, but what matters more is whether the grill reaches and holds the temperature you set. Look for even flame coverage across the burners and minimal hot spots. A grill that can reach at least 500°F is adequate for searing; 600°F is better for high-heat cooking.

Construction quality determines how long the grill lasts. Double-walled or well-insulated lids and body panels hold heat better and cook more evenly. Stainless steel, cast-iron grates, solid welds, and a heavy lid are signs the manufacturer did not cut corners. A thin metal lid bleeds heat, creates hot spots, and rusts faster.

Features are only useful if you actually use them. Side burners, warming racks, and rotisserie kits add cost. On lower-priced grills, extra features sometimes hide weaker burners or thinner materials. A simple, well-built two-burner grill is better than a five-burner model with flimsy construction.

Common Mistakes and Safety Basics

The most frequent buying errors: choosing by BTU alone, picking a grill too big or too small for your crowd, and paying for features you do not need while accepting weak burners or thin metal. Do not overlook hot spots or poor lid insulation — a grill that cannot hold steady temperature ruins even the best steaks.

For safety, verify your grill is compatible with your fuel type before hooking it up. Keep a fire extinguisher nearby, never use water on a grease fire, and use a meat thermometer to confirm food is fully cooked. If you are not confident in your setup, a professional installation ensures everything is connected correctly.
